Does reduction in pulse indicate reversal of LA/LV enlargement

[Tinu1959]

My resting pulse rate has reduced from 80 +/- 5 to 70 +/- 5 during last one month and during this period dose of medicines including beta blockers and ACE-I remained unchanged. My BP(110/70) and activities also remained consistant during this period. My echo one month back indicated enlargement of LA/LV and moderate MVR. I suffered ischemic heart attack about 9 months back with LV disfunction and 30% EF. I am feeling better over this period.

My question is "does reduction in pulse rate indicate stop on further increase in LA/LV size and MVR or begining of its reversal??" In any case, is it a positive sign or does it reflect some further complication of disease??

Thanks in advance.

LV enlargement (dilated) is an indication the heart is overworked and untreated the heart rate would also increase.  If the heart size is reduced (reverse remodeling) contractions (stroke) would/could be stronger.  A stronger heartbeat should/would  increase the cardiac output and require fewer heartbeats given the same demand.  It can be seen in an equation where cardiac output is stroke (amt of blood pumped with each heartbeat) times the number heartbeats in a 60 second interval...increased stroke fewer heartbeats, a decrease in stroke (weak heart) more heartbeats to meet the same demand.
